Good evening everyone
I'm trying to get an old 151 operational for a friend, this is a cut mutt

Problem is no turn signals, no brake lights, no tail lights, I do have headlights high and low beam and dash lights. This has an old style relay box under dash, close to where the turn signal flasher goes metal box with ten wires attached to it on the exterior using two sets of screw on wire connections. bus is about the size of a old cigar box. inside is three relays, and black rectangle about 4 inches long appears to be a snap in. Flasher unit ?? anyway I think I should modernize what else can I use. or does someone have one of these boxes? I don't want to put a lot of money into this. Looks like this mutt was put together on a budget but quality of workmanship not bad.
